UniApp是一个基于Vue.js框架的跨平台应用开发框架,可以同时开发iOS、Android、H5等多个平台的应用。"put"是HTTP协议中的一种请求方法,用于向服务器上传资源或更新已存在的资源。在UniApp中,如果需要将数据保存到服务器或更新服务器上的数据,可以使用HTTP请求中的"put"方法来实现。具体的使用方法可以参考UniApp的文档或相关教程。

uniapp 如何使用put更新的网络请求
在uniapp中使用put请求更新数据需要以下步骤:
1. 引入uni-request库:可以通过npm安装或手动下载后放到项目中。
2. 在需要使用的页面或组件中引入uni-request库:
```javascript
import {request} from '@/common/js/request.js';
```
3. 使用request进行put请求:
```javascript
request.put('/api/user', {
name: 'Tom',
age: 20
}).then(res => {
console.log(res.data);
}).catch(err => {
console.log(err);
});
```
4. 在request.js中定义put请求方法:
```javascript
import Request from './http.js';
const request = new Request();
request.interceptor.request((config, cancel) => {
// 发送请求前的操作
return config;
});
request.interceptor.response((response, cancel) => {
// 响应数据操作
return response;
});
// 定义put请求
request.put = (url, data) => {
return request.request({
method: 'PUT',
url: url,
data: data
});
};
export {request};
```
以上就是uniapp中使用put请求更新数据的基本步骤,需要注意的是,请求参数data需要根据接口文档进行相应的调整。
uniapp request
Uniapp is a framework that allows developers to create cross-platform applications using HTML, CSS, and JavaScript. In order to make requests in a Uniapp application, developers can use the built-in uni.request method.
Here's an example of how to make a simple GET request using uni.request:
```
uni.request({
url: 'https://jsonplaceholder.typicode.com/todos/1',
success: (res) => {
console.log(res.data)
},
fail: (err) => {
console.log(err)
}
})
```
In this example, we're making a request to the JSONPlaceholder API to retrieve a todo item with an ID of 1. The uni.request method takes an object as its argument, with various properties that can be set:
- `url`: The URL to make the request to.
- `method`: The HTTP method to use (default is GET).
- `data`: The data to send with the request (for POST, PUT, etc.).
- `header`: Additional headers to send with the request.
- `dataType`: The expected data type of the response (e.g. JSON).
- `success`: A function to be called if the request is successful.
- `fail`: A function to be called if the request fails.
In our example, we're only setting the `url` property and the `success` and `fail` callbacks. When the request is successful, the `success` callback is called with the response data as its argument. If the request fails, the `fail` callback is called with an error object as its argument.
Uniapp also provides other methods for making requests, such as `uni.uploadFile` for uploading files, and `uni.downloadFile` for downloading files. These methods work similarly to `uni.request`, but with additional options specific to their use cases.
